With the continuous breakthroughs in science and technology, more and more biological characteristics of people are applied to various industries. For example, common fingerprint recognition, face recognition, iris recognition, vein recognition and so on. Biometric technology is a close combination of computer and optics, acoustics, biosensors and biometric principles and other high-tech means, using the inherent physiological and behavioral characteristics of the human body to identify personal identity.

Fingerprint identification technology

Fingerprint identification technology is to identify by comparing the characteristics of different fingerprints. Each person's fingerprint is unique, and if the similarity of the fingerprint is more than 99%, then a person can basically be identified as the same person. As the fingerprint identification instrument is simple and fast to operate, it is widely used in the field of biological authentication, mainly for company attendance, security, identity authentication, bank vault system and so on. Even today's mobile phones and computers use fingerprint recognition.

Then there is face recognition technology, which is often referred to as facial scanning. Later, after Ma Yun introduced face recognition technology to Alipay, he realized "facial scanning to eat". Everyone's face images are different, and even twins' brothers can distinguish them through face recognition technology.

Face recognition technology

According to the different facial features, face recognition technology uses a special biometric algorithm to identify whether it belongs to the same person. However, in this face-sweeping stage, the scope of application is not too wide, after all, it is much more harmful to people's privacy than fingerprint identification.

Iris recognition technology

The characteristics of iris can be seen that everyone's iris is the same as fingerprints, which is not only unique, but also will not change without special circumstances. As long as human beings realize iris recognition technology, this technology will be applied to various scenes. Iris recognition technology is more accurate and faster than fingerprint recognition technology.

Vein recognition technology

Finally, palmar vein recognition technology is a highly safe biometric technology. Its working principle is that the palm vein distribution eigenvalues collected by the near-infrared sensor are encrypted and processed into irreversible computer data and stored in the database. When identity authentication is needed, the metacarpal artery data are collected and compared with the templates in the data to authenticate personal identity.

With the development of the times and the continuous progress of technology, biometric technology has solved a basic identification problem in the daily life of human society. In the future, the results of this identification will be more and more combined with the applications of various industries, and the information will be shared through the network.
